    Abstract: A disk drive is provided for restraining deterioration of the verticality of the optical axis of an optical pickup in relation to the surface of the disk when the side of the disk to be scanned for the recording and/or reproducing action is alternated from one side to the other side, in recording and/or reproducing data signals on both sides of the disk. The disk drive (1) includes a turn table (11) on which a disk D is rotatably supported, a pickup (12) for recording and/or reproducing data signals on both sides of the disk D rotated by the turn table (11), and a disk tray (31) for transferring the disk D between a recording and reproducing position which confronts the turn table (11) and a loading and unloading position at the outside of the disk drive (1). A turning movement mechanism is provided for turning the turn table (11) and the pickup (12) at once from a first position which confronts the one side of the disk D to a second position which confronts the other side of the disk D or vice versa.

    Abstract: For providing an optical disk driving device that is capable of accurately performing recording and reproduction of even disks that include warpage without the provision of a tilt mechanism, a clamper is comprised of a central clamper portion for pinching and holding a disk between the clamper and a turntable, and an outer clamper portion for abutting against an outer periphery of the disk and pressurizing the same in case the disk includes any warpage to thereby correct the warpage. It is accordingly possible to restrict an angle formed between a light beam and an information surface of the disk to be within a specified value for accurately performing reproduction.

    Abstract: A disk transfer device including a disk tray for holding a disk during the disk transfer action and a tray driving mechanism for driving the tray forward and backward between a first position which is the retracted location of the tray corresponding to a turntable in a disk drive and a second position which is the loading and unloading location of the disk outwardly of the disk drive. The disk tray is provided with a large diameter support region and a small diameter support region which is stepped down by a predetermined distance from the large diameter support region. A plurality of claws capable of engaging with the peripheral edge of the lower side of a small size disk are provided on the outer periphery of the small diameter support region. When the small size disk held and pinched between the clamper and the turntable is unloaded from the turntable, the peripheral edge climb over the claws, thereby, the disk is moved toward the turntable and released from its held state between the clamper and the turntable.
